CLUSTER MESSENGER-NUMBER-PHONE · 16 ENTRIES · EARLIEST ENTRY 2018-03-30

Anonymous encrypted messengers

This cluster comprises private messengers that use encryption and allow signup without a phone number or email, offering text, calls, and file sharing, with some additions like a wallet or multi-device support. The dated entries span from 2012 to 2026, with single entries in 2012, 2018, 2021, 2022, and 2025, and a higher number of monthly entries in 2026, including four in June 2026. SimpleX Chat is the top traction leader, followed by Vutalk and Zyphr, all with zero stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
